SOUTH BEND, Ind. -- Coach Brian Kelly says running back C.J. Prosise has been cleared for physical activity after sustaining a concussion. He still needs to pass another test before a decision is made on whether he will play against Wake Forest on Saturday.

Prosise was injured in a 42-30 victory over Pittsburgh on Saturday when he landed hard on his left shoulder and his helmet hit the ground. Kelly previously described it as a "whiplash effect." Kelly said Prosise would need to be cleared by Wednesday if he's going to play Saturday.
